From 76bbc5d26459c29e1d8ef7af014f90dff8183a07 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3854/4131] drm/amdgpu: Fix always_valid bos multiple LRU
insertions.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If these bos are evicted and are in the validated list
things blow up, so do not put them in there. Notably,
that tries to add the bo to the LRU twice, which results
in a BUG_ON in ttm_bo.c.
While for the bo_list an alternative would be to not allow
always valid bos in there, that does not work for the user
fence.
v2: Fixed whitespace issue pointed out by checkpatch.pl
